Refractive Accuracy of "2WIN" and Portable Autorefractors

Completed

Conditions studied: Refractive Error - Myopia Axial, Astigmatism, Accomodation, Visual Impairment, Hyperopia of Both Eyes

In brief

Youth and some adults have photoscreening refractions and hand-held auto refraction before cycloplegia refraction during new and follow up eye examinations. Vector math is applied to each refraction to determine how closely the hand-held "dry" devices match actual refraction.
